利用移动交换中心直接播放彩铃的方法研究

摘要

彩铃业务自发展以来，由于其业务特点及当时的技术条件决定了其业务的提供方式，即通过在网络中引入专门提供彩铃业务的平台来开展彩铃业务。利用移动交换中心直接播放彩铃的方法，则不再需要另外发起一次指向彩铃平台的彩铃呼叫，不再需要在移动通信网内再建设彩铃呼叫平台，在节省大量系统建设成本的同时，彩铃接续中又减少了一次指向彩铃平台的彩铃呼叫，进而提升了移动通信网的运行效率。%The operational characteristics and current techniques determine the service supply methods of CRBT, that is, we build the CRBT business by introducing to the color ring service platform on the network. While using the method of playing color ring by mobile switch center,we don’t need another call which point to color ring service platform.Furthermore,we don’t need establish color ring service platform in mobile communication network.This method not only saves costs of system construction but also enhances the effi ciency of mobile communication network by reducing one call which point to color ring service platform from subsequent call.
